.Many word processors handle RTF formats, so you can save an RTF document from your favorite word processor and then run RTFTOHTML against it.RTFTOHTML is available through anonymous FTP from ftp.cray.com in the directory src/WWWstuff/RTF.Through the Web, try http://info.cern.ch/hypertext/WWW/Tools and look for the file rtftoftml-2.6.html (or a later version).Maintaining HTMLOnce you have written a Web document and it is available to the world, your job doesn't end.Unless your document is a simple text file, you will have links to other documents or Web servers embedded.You must verify these links at regular intervals.Also, the integrity of your Web pages should be checked at intervals, to ensure that the flow of the document from your home page is correct.Several utilities are available to help you check links and to scan the Web for other sites or documents you may want to provide a hyperlink to.These utilities tend to go by a number of names, such as robot, spider, or wanderer.They are all programs that moves across the Web automatically, creating a list of Web links that you can access.(Spiders are similar to the Archie and Veronica tools for the Internet, although neither of these cover the Web.)Although they are often though of as utilities for users only (to get a list of sites to try), spiders and their kin are useful for document authors, too, as they show potentially useful and interesting links.One of the best known spiders is the World Wide Web Worm, or WWWW.WWWW enables you to search for keywords or create a Boolean search, and it can cover titles, documents, and several other search types (including a search of all known HTML pages).A similarly useful spider is WebCrawler, which is similar to WWWW except that it can scan entire documents for matches of any keywords and display the result in an ordered list from closest match to least match.A copy of World Wide Web Worm can be obtained from http://www.cs.colorado.edu/home/mcbryan/WWWW.html.WebCrawler is available from http://www.biotech.washington.edu/WebCrawler/WebCrawler.html.A common problem with HTML documents as they age is that links that point to files or servers may no longer exist (either because the locations or documents have changed).Therefore, it is good practice to validate the hyperlinks in a document on a regular basis.A popular hyperlink analyzer is HTML_ANALYZER.It examines each hyperlink and the contents of the hyperlink to ensure that they are consistent.HTML_ANALYZER functions by examining a document to all links, then creating a text file that has a list of the links in it.HTML_ANALYZER uses the text files to compare the actual link content to what it should be.HTML_ANALYZER actually does three tests: it validates the availability of the documents pointed to by hyperlinks (called validation); it looks for hyperlink contents that occur in the database but are not themselves hyperlinks (called completeness); and it looks for a one-to-one relation between hyperlinks and the contents of the hyperlink (called consistency).Any deviations are listed for the user.HTML_ANALYZER users should have a good familiarity with HTML, their operating system, and the use of command-line driven analyzers.The tool must be compiled using the "make" utility prior to execution.There are several directories that must be created prior to running HTML_ANALYZER, and it creates several temporary files when it runs that are not cleaned up, so this is not a good utility for a novice.SummarySetting up your home page requires you to either use an HTML authoring tool or write HTML code directly into an editor.The HTML language is beyond the scope of this book, but you should find several good guides to HTML at your bookstore.HTML is rather easy to learn.With the information in this chapter, you should be able to set up your Web site to enable anyone on the Internet to connect to you.Enjoy the Web!
